I pacifically remember last time i went to the doctors for a check up, the questionnaire of personal info asked for sexual orientation. When?

did sexual orientation become gender? And why does gender mean the same thing sexual orientation used to mean which was whether you are a male or female. If your a dick who cannot answer or doesn't know and makes me feel stupid or a troll who doesn't know the answer and is a dick, i will write retard to f*cking retard under your answer because i am looking for a simple answer, not a retarded answer. Last time i got a check up was 2010. FYI, i have not been sexually active since then incase you wanr to have a beef about that.
